Webto exist. Statistical power is determined, in part, by effect size and sample size. 2.1.2.2.1 Effect Size as a Determinant of Power . As noted earlier, each random sample taken from a population has its own mean and variance. The . distribution of means. is the distribution of all possible means of samples that could be taken from the population. WebSample size determination is the act of choosing the number of observations or replicates to include in a statistical sample.The sample size is an important feature of any empirical study in which the goal is to make inferences about a population from a sample.
